Which of the following types of glial cells monitors the health of neurons, and can transform into a special type of macrophage to protect endangered neurons?

- ependymal cells
- astrocytes
- microglia
- oligodendrocytes

Microglia is a type of gllial cells that monitor health of neurons and can transform into special type of microphage to protect endangered neurons.

Explanation:

Gllial cells are cells found in the nervous system, they surrond the neurons and provide support and insulate them.

Types of gllial cells include, microglia, Schwann cells, satellite cells, ependymal cells, astrocytes and oligodentrocytes.

Microglia is a type of gllial cells than can change to special macrophages found mainly in the central nervous system. The maintain the health of the nervous system and protect endangered neurons. They also removed damaged neurons.
